IMPROVEMENT IN ROCKING DEVICES FOR HARVESTERS.

Specification forming part of Letters Patent No. 192,681, dated July 3,1877; application tiled May 21, 1877.

To all whom it may concern:

Be it known that I, EDWARD CHENEY, of Geneva Lake, in the county ofWalworth and State of Wisconsin, have invented a new and ImprovedTilting Device for Harvesters, of which the following is aspecification:

Figure l is a side view of my improved tilting device. Fig. 2 is a topview in detail.

Similar letters of reference indicate correspondin g parts.

This invention relates to means for tilting the cutting apparatus ofreaping and mowing machines; and the nature of my invention consists incombining, with the draw-bar and slotted shoe of the finger-bar, anadjustable cam or slotted wedge and a hand-lever, whereby the attendantcan tilt the cutting apparatus', and give it any desired angle ofinclination, as will be hereinafter explained.

In the annexed drawing, A designates the cutting apparatus of a reaperor mower, and

B is the inner shoe, which is slotted vertically, and extended from thefinger-bar forward and upward, as shown in Fig. l. G designates adraw-bar, which is pivoted between ears a, formed on the shoe B, andalso pivoted to the draft-frame. This draw bar will allow the cuttingapparatus to be tilted, and it will also allow it to be raised anddepressed. D designates a cam or slotted wedge, which is connected byclips b b to the draw-bar O, and which is free to be moved on this barin a direction with its length. The slot 0 in the cam is curved, asshown in Fig. 1, and receives an anti-friction roller, d, which isapplied to the upper end of the shoe B. The cam or slotted wedge D haspivoted to it a rod, E, which is connected to a hand-lever, F, arrangedin a position convenient to the drivers seat.

It will be seen from the above description that by vibrating the lever Fthe cam D is moved on the draw-bar, and the cutting apparatus is tilted.The cam acts positively on the shoe of the finger-bar, and the roller dprevents undue friction.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- The slotted cam or wedge D, adjustable on thedraw-bar O, and combined with the shoe B, substantially in the mannerand for the purpose described.
